Application filed May 24,

Frames for Bosh; and I do declare the fol lowing to be a full, clear, and exact description of the invention, such as Wlll enable others skilled in the artto which it ap-v.

pertainsto make and use the same.

This invention relates to an improved plate holding frame foruse in connection with a bosh or tank in which sheets of tin plate" are to be placed while being conveyed from the pickling machine to the tinning machine. In manufacturing tin plate, the plates are treated in the pickling machine and when removed they are immersed in water in a tank or'bosh While being conveyed to the tinning machine so that the plates which have been pickled cannot become rusted while being conveyed from the pickling ma-' chine to the tinning machine.

According to present usage in tin plate mills, the plates are placed vertically within the tank and when removing the tin plate from the tank for further treatment, the entire service of one man is required to remove the tin plate and place it in a pile near the tinner who takes the tinplate from the pile and places it in the tinning machine. Removal ofthe tin plate from the tank for further treatment requires that the person moving the tin plate stand beside the tank, whereas it is well known that the person giving attentionto the tinning of the metal must be beside the machine or place of treatment. Thus, for removing the metal from the tank the entire time of another man is required, in addition to the person operating the machine or giving attention to the treatment of the metal.

One object of the invention is to provide a frame for use within the tank, whereby the service of the additional man required to remove the tin plate from the tank may be dispensed with.

Another object of the invention is to so construct this frame that it may fit into a bosh of a conventional construction thus permitting it to be sold as a separate. article and simply used in connection'with tanks already in use.

Another. ob ect of the invention is to so 1921. Serial No. 472,090. 7

construct this frame that plates of different sizes may be placed in the frame,- gage pins or stakes being 'removably carriedfby the bottom of the frame so that theplates may be easily placed in the frame in the proper positions. Y

Another object of the invention is to provide a frame so constructed that the plates may be passed into the frame at'the open front thereof and drawn out of thefra'me through the open end thereof, thus making the frame so constructed thatthe plates may be easily handled and slipped into the frame I in a horizontal position; where they will be 0 piled. one upon the other and also drawn out of the frame in ahorizont'al. position so that they can be easily handled and. passed into thetinning machine.

Another object of'the invention is to provide 'frame of the character; 1 described which willbe cheap to produce and. strong and durable and easy to operate.

This invention is f illustrated in the .accompanying drawings, wherein:

rectly upon the ground or upon any suit- 1 able support desired. The'frame which is ,to carry the tin plates taken from the pickling machine is provided with a bottom 3, an end wall 4 and a rear wall 5, these walls and the bottom-being provided; with open- 105v ings 6 so that water can readily passthrough these walls when thefframe is in the tank or bosh 1. It will be further noted that the bottom is provided with openings 7 which extend in spaced rows parallel to 11.0"

.00 This improved tin. plate carrying frame 15 used in connection with a bosh or tank 1 1 which is of a conventional construction the end wall a and rear wall and are intended to receive the reduced lower end porframe.

' andhas its upper end portion flattened to tions ofstakes 8 which willbe-placed in the framewhen necessary according to the size of plates which are to be'placed inthis This frame. is provided with a 1 corner post 9 which is secured to the bottom provide ahead 10 which will be secured between the angle irons which are secured together by rivets and provide across-bar 11 which extends diagonally across the upper 'end of thejframe and has 1'68 second end portion secured by rivets to the bracket- 12 formed from a strip of sheet metal, the

end'portions of which are bent so that they will extend downwardly and may be connected with the rear and end walls of the frame. A second cross-beam which is also formed of angle iron extends diagonally of the frame 'substantiall at ri ht an les to the" cross-beam 11 and is provided with end sections 13 which have theirouter end portions connected with the supporting bracket 14 carried bythe walls 4 and 5 and their innerend portions connected with the cross beam 11 by angle brackets 15. In ad dition to providing the angle brackets 15 for connecting these cross bars, there has been provided a plate 16 which is positioned beneathand secured to the und'erfaces of be readilyseen that when the hook 20 en-' the cross beams. 7 there has been provided a tank which will be open at one end and in front and also open at its upper end and further that there has been provided a tank having the bottom and walls perforated so that water in the tank or bosh can easily circulate. In order t-opermit the frame to belifted from the tank or bosh by means of the hoistingtackle indicated in general by the numeral 17, there has been prov ded a plate 18 which is secured between the angle iron bars which form the cross bar 11. This plate is provided with an opening or eye 19 and it will gages the eye 19, the hoisting tackle can be operated to draw the fraine'upwardly out of the tank.

l/Vhen this device is in use, the tank is placed close .tothe pickling machine and as the sheets of tin plate are removed from.

the pickling machine, they are passed into theirame through the open front and will restfiat-in theframe in a horizontal position'and be piledpne upon another. If large plates are being handled, the stakes 8 will not be put in'pla'ce as these large plates will occupy practically the entire interior of the frame. When however smaller plates are being handled, the stakes will be placed in openings 7 in the-proper rows and when the plates are' placed in the frame, they will be brought'into engagement with the rows of stakes. When the frame is It will thus be seen that completely filled with the plates of sheet metal, the tank containing the frame and which will of course beli'lled with water above the height of the plates, will be lifted by .-means ofa suitable crane and will be carried over to the tinn ng'machine wher hook 20 of the hoisting device 17 can be passed throughthe opening 19 and the frame will be gradually lifted out of the it will. be lowered and left in position. The V tank.- As the frame is drawn, upwardly, i the plates will beremovedthrough the open end of the frame andas the operator, or

tinner as he is known', draws the plates from the frame, he will mmedla tely place the'm in the tinning machine. When the plates have all beenfremoved' from the frame 7 and placed in the tinnmg' machme, the

frame can be again lowered 'into the tank and thetank returned to the original position in operative relation to the pickling machine, it will thus be seen thatgthere has been provided a frame for use in connection with a ,bosh tank which 1s so constructed that the sheets of tin plate can be Very easily and qu ckly put into the frame and held in a horizontal POSltlOD where they are not liable to become bent at thecorners and further that with this arrangement .a

single operator can remove the sheets of tin plate'from the frame and place them 1 in the tinning'machine.- A, great saving is thus accomplished since the services'of an assistant for the tinnercan be. dispensed with and the necessity'of piling of the plates the tinner before placing them in the tin-,

nin'g machine can be done away with.
